Specific provisions relating to trichloroethylene (TRI) (No 121) (*)

A two-axle group is called a tandem and a tri-axle group a tri-axle bogie. By convention, a solo axle is considered as a group of one axle.

(a), 5 m3/tonne of TRI + PER production, - (b), 2 m3/tonne of TETRA + PER production.

Silylating reagent, for example TRI-SIL (available from Pierce Chemical Co, Cat No 49001) or equivalent (Important: TRI-SIL is inflammable, toxic, corrosive and possibly carcinogenic.

THE SAMPLE IS EXTRACTED WITH A DILUTE METHANOL SOLUTION OF TRI (HYDROXYMETHYLAMINO) METHANE.

the weight on any tri-axle at the spacing specified in point 3.3.2 does not exceed 22,5 tonnes,

For existing plant using dehydrochlorination of tetrachloroethane, the capacity of production is equivalent to the capacity of TRI-PER production, the ratio of TRI-PER production taken at one third.

Laboratory personnel must be familiar with TRI-SIL safety data and take the appropriate precautions.)

Elimination of buprenorphine is bi- or tri-exponential, and has a mean half-life from plasma of 32 hours.

Telithromycin displays a tri-exponential decay from plasma, with a rapid distribution half-life of 0.17 h.

The limit of determination for TRI is 10 mg/litre for effluents and 0,1 mg/litre for the water environment.

DETERMINATION OF WATER-INSOLUBLE SUBSTANCES PRESENT IN MONO-, DI- AND TRI-SODIUM ORTHOPHOSPHATES AND MONO-, DI- AND TRI-POTASSIUM ORTHOPHOSPHATES (E 339(i), E 339(ii), E 339(iii), E 340(i), E 340(ii) AND E 340(iii))

Determination of water-insoluble substances in mono-, di- and tri-sodium orthophosphate and mono-, di- and tri-potassium orthophosphates (E 339(i), E 339(ii), E 339(iii), E 340(i), E 340(ii), E 340(iii)) using Annex II, method 14.

An example of a widely used neurotoxicant is tri-o-tolyl phosphate (CAS 78-30-8, EINECS 201-103-5, CAS nomenclature:

The Member States concerned will establish regularly the relationship in concentration between TRI and the parameter used.

Benzyl alcohol Sodium acetate (tri-hydrate) Acetic acid, glacial Sodium chloride / Hydrochloric acid 4N (for pH adjustment)

Without prejudice to the provisions of heading A (4) in Annex I, TRI limit concentrations relate to the following reference values:

Aliphatic and aromatic mono- and di- thiols and mono-, di-, tri-, and polysulfides with or without additional oxygenated functional groups.

For sectors (a) and (b) the limit values for PER discharges relate either to overall TRI + PER production capacity or to overall TETRA + PER production capacity.

a lower sulphur content reduces emissions of particles and increases the conversion efficiency of oxidising catalysts, and the reduction in di- and tri-aromatic compounds reduces the formation and emission of PAHs.

Article 5 of Directive 86/280/EEC applies in particular to TRI used as a solvent for dry-cleaning, for the extraction of grease or odours and for degreasing metals where annual discharges amount to less than 30 kg/year.

Member States may determine concentrations of TRI by reference to the quantity of AOX, EOX or VOX provided that the Commission is first satisfied that these methods give equivalent results and until the general solvent Directive is adopted.

The reference method of measurement to be used for determining the presence of trichloroethylene (TRI) in effluents and the water environment is gas chromatography with electron capture detection after extraction by means of an appropriate solvent.

The absorption of doxycycline from the gastro-intestinal tract may be inhibited by bi- or tri-valent ions such as aluminium, zinc, calcium (found for example in milk, dairy products and calcium- containing fruit juices), by magnesium (found for example in antacids) or by iron preparations, activated charcoal, cholestyramine, bismuth chelates and sucralfate.

Pharmacological interactions Caution should be exercised in coadministration of fesoterodine with other antimuscarinic agents and medicinal products with anticholinergic properties (e. g. amantadine, tri-cyclic antidepressants, certain neuroleptics) as this may lead to more pronounced therapeutic- and side-effects (e. g. constipation, dry mouth, drowsiness, urinary retention).
